C. WEST SIGNALING APPARATUS FiledApril 29, 1959 2 Sheets-Sheet 2 related to a Patented July 15, 1941 UNITED STATES PATENT OFFICE -sIGNALING APPARATUS n Chester West, Brooklyn, N. Y. Application April 29, 1939, serial No. 270,734 2o claims; (ci. 11s- 160) 'I'his invention relates to signaling apparatus, particularly of the type for association witha door, or the like, whereby a caller may announce himself.

One of the objects of this invention isto pro,-

.vide a simple, inexpensiveand practicalaudble signaling apparatus that will beof pleasing sound and capable of easy and rapid installation.` Another object is to provide a signaling apparatus which, as to its individual parts, may be inexpensively manufactured and whichv individual parts are capable of rapid and inexpensive assembly. Anotherobject is to provide a signaling apparatus of the chime type thatmay be embodied in small and compact form, maybe installed easly. and quickly, is unobtrusive inappearance where it is mounted inV an exposed position and which, moreover, may be mounted in small or out-of-the-way spaces. Another object is to provide a signaling apparatus of the' above-mentioned character which may be readily incorporated into, for example, the hollow frame of a door so as to be thus out vof the way and to. occupy what is otherwise waste space, and which in construction and operating mechanism is simple and dependable and free from lliability of becoming' disarrang'ed. -Another object is to provide a signaling apparatus whichrnay be related directly to a dooror door panel .and be Vneat in appearance'and foolproof in construction Yand'mounting. Other objects lwill, be in Ypart obvious or'in part pointed out hereinafter; The invention accordingly consists in the fea'- tures of construction, combinations of elements, and arrangements of parts as will' be exemplified in the structure to be hereinafter described and the scope of the application of which will be indicated .in the following claims.

In the accompanying drawings in which I have shown' oneV of various possible embodiments of lmy invention, with illustrative possible modifications of certain features of construction,

Figure 1 is acentral vertical sectional View lthrough a signaling apparatus, as mounted or suitable support, such as ardoorV panel; l Y I j Figure A2 is a detailed sectional view alongthe Vline 2 2 of Figure l; c

AFigure 3 is an elevation as seen along the line Figure l is a front elevation, as seen, for example, from the front;V of a door panel, Vshowing III being thus made to round,- and slidable in the Walls of yits center, a sleeve member II of relatively small outside diameterY so that it may be fitted or passed through a hole I2 cut or drilled in the supporting member which, in Figures 1 and 2, is indicated at I3,; and may take the form of part of a door, such asa panel thereof, the door being, for eX- ample, the door of an apartment, house, or the like, the sleeve member take part in mounting the signaling apparatus in place; for that purpose the outer end of the sleeve I I may be threaded as at I4 to receive a nut I5 which, when tightened up, clamps the panel I3 -between itself and the main plate I0. Y

The connection between sleeve II and plate I0 may be elfected in any suitable way and in Figure 1 is; shownas taking the form of a threaded connection, as at I6, the plate I0 having a threadedaperture for that purpose to take the threads at the left-hand' end of the sleeve II; thisthreaded connection I6 is preferably a tight connectionor maybe made tight by heading over or expanding the left-hand end portions of the ksleeve II,.thus to insure` that the parts II and I0 are non-rotatively secured together.

At its right-hand end the sleeve I I has an end wall Il providedhwith an aperture I8,preferably the aperture I8 is a push button I9 preferably made of sheet metal and preferably so constructed that it is assembled to the sleeve I I from the inside or lefthandl end thereof. Y

T hus, thepush button I9 may have a llange 20 at its `inner end, the latter preferably also limiting the extent of movement vof the button I9 outwardly or towardtheright under a suitable spring pressure, as later described.

Thepush buttonsl9, ,the nut I5, and the vexposedunthreaded portions of thesleeve .II may be finished off 'in any suitable Way to harmonize y with the finish or `decoration of the face of the vinem-ber I3 from which these parts vproject* and thus inconspicuousness and neatmess of appearance may -be gained.

II with the main-'plate Carried, preferably in a manner later described, from the inner face of the main plate IB, is a striker 2| which is to set into sound-producing vibration suitable means which preferably and illustratively take the form of two so-called chime bars 22, 23 which are mounted preferably parallel to each other (Figure 3) and in spaced relation, with the striker 20 therebetween in order that, in this preferred form, the striker 2| may coact with both when suitably swung or moved to impact one or the other or lboth. Wherethe striker 23 is to act upon two sounding elements, like the chime bars 22 and 23 the sounding elements may be of different pitch and hence may sound two diiferent notes or tones. f

anchored in any suitable way, but preferably so as to tend to hold the upper end portion of the spring arm 32 vertically and thereby always to bias the striker 2| to a position midway of the two sounding elements 22, 23, and hence biassed to a position spaced from either.

The mounting of the spring arm 32 is such that it extends downwardly in front of the disk member 3| and the latter has projecting therefrom a lug 34 which has an aperture 35 through which fthe spring arm 32 passes, the two side walls of the aperture 35 thus providing two spaced members, one on each side of the spring arm 32, by which the latter may thus be flexed Depression of the push button I3 in Va direcy tion inwardly of the sleeve is to set the striker 2| into motion to impact one-or the-other or both of the sounding elements and a preferred form of mechanism for achieving this responsive action -is as follows: f

Button i9, which is cylindrical, is arranged to coact with a cylindrical drum or shaft24vof a diameter to make a sliding fit with the interior of the buttonl |3 -sothat the twoparts mutually guide Vand support each other during v.their -respective movements. Drum shaft 24 has a-helical slot 25 into which takes a pin or lug 25 carriedv by and projecting inwardly-of the left-hand end of button i3, as is better shown in Figure 1, andl before Aentering the right-hand end of drum shaft 24 into the left-hand end of button |9, during assembly, a helical spring |26 is entered into the button I9. Inward movement of button I9, if unaccompanied byrotation, thus ef- `fects a rotary movement of the `drum shaft 24 by the coaction of pin 26 and helical slot 25, the latter two parts being duplicated preferably and spaced 180 apart, as indicated in Figure 1. Any

suitable means may be employed to hold button 19 against rotation and illustratively its `flange 23, as is better shown-in Figure 2, may have two cutouts or slots 23a and 2Gb, preferably 180 apart, in which are accommodated internal longitudinally extending ribs lia and Il", prefer- './1

ably integrally formed with the sleeve The left-hand end of drum shaft 24 is stepped as at24a, and is lprovided with a combined rotary andfthrust bearing in the form of an aperture 2'! in a `plate 28 (Figures 1 and 3) which bridges and closes over the left-hand otherwise open end of the sleeve and is secured to the main plate M) in any suitable way, as byV screws 29. Thus, thrusts exerted on the drum shaft 24 in a direction toward the left, as-viewed in Figure 1, are taken up by the plate 28, while axial move- 'ment of the drum shaft 24 in a direction toward the right is prevented by the hub 30 of a striker vactuating 'member which preferably takes the form of a disk 3|, preferably coacting with the striker 2| in a manner later described. Thus, after plate 28 has been put in position, the-member 3| is mounted on the reduced end 24e of the drumv shaft 24 and its hub 30 secured thereto in any suitable manner, as by a drivingt, a set Y screw, or the like.

Y .The'striker 2|, which -may be madefof any suitable material, such'as wood or molded plastic, is `preferably mounted on a springfarm- 32 made of a suitable -springy metal, like flatwire of steel,phosphor bronze, lor the like, and its -upper endissecure in any suitable way'to the main 4platefHL-as by a stud 133 'which maybe '-xed to the plate I'U 'in any .suitable-way and 2to "'hi'ch the upper end of the spring arm 32is-clampedfor I in Aeither direction relative to the fixed axis prostud 33. 3| is connected to the drum shaft .vided by the The disk v 24in such angular relation to the normal positionV of the pin 26 along the slot 25 that the part 34 '(see Figure 3) is to the right of the vertical 1plane through thel axis of the disk member 3|, thus biassing the spring rarm 32 in counter-clockwisedirection about the stud 33 and thus holding the striker 2| in close proximity to the sound- -ingelement.23; the spring |25. (Figure 1) inside the button-I3 has sufficient stiffness to insure Ithatthis relationship..is.established and main- -tained.r:..;.j 1 Y v Accordingly, when button I9 is pressed inwardlyfof the-sleeve i |.against the spring |26 which Ytherebyzhas `energy stored in it, the pinand vslot connections 26-125 effect a relatively quick rotary movement of the-'drum shaft 24 and hence also ofthe disk3| throughout' a suitable extent, illustratively, throughout about 1A Vturn or 90, thus warpingthe spring arm 32 from the general position as .shown in .Figure 3 to a position 'toward the left to impact Vthe sounding element 22, the maximum-amount of permissible rotary movement of the drum shaft 24 being preferably such that., an energetic impact or 'blow `results withsuicient leewaylfor reboundl of the striker 2| Y.from the element 22, so as not to dampthe Yvibrations* of the latter; release of the push but'- ,ton ,|9; permits the expenditure of theY energy 'stored' in the spring |26 and also in the tensioned springa'rm 32, Lthus to. effect a rapid reverse rotation vof the rotary parts and therebyfto effect a similar impactof the'striker 2| .against the sounding element 23., theY striker .2| upon rebound assuming aposition substantially as shown in Figure 3. ,It;will be understood, 'of course, that the springiness -ofzthe spring arm` 32xin relation to the weight offthe striker 2| itself is preferably suchas to givezit vsubstantial resiliencev or elas- `|.icity..,.- 1 Preferably, the just described -actionsare ac'- companied by a snap action and it is preferably on Athat account that the 'striker-'actuatingmember "preferably, ,takes the form lof 'the .disk 3| :as above described. Substantially. diametrically opposed from the part 34 yon the `disk3| Vis -a pro jection v36 of suitable conformation to project into the path of swing vofthe spring arm 32but of insufficient `projection to prevent the spring arm 32 from yielding or bending lout of -its plane of swing sufficiently so as thereby tosnap olf ofthe `side face of `the' projection 3 5.; Wherefthe'stiiker 2| is related to two soundingelements'like the elements `22'ar1d 23, the projection "36, isfdouble acting, its left-hand and right-hand faces, vas viewed in FigureS, being' simil-arly sh'ape'dso as .to present'the sameidegreeof resistance t'o` bypassing from eitherfvsidre of-the member 1361 .Accordingly, "when-'the button `|9 is depressed 'whence the mounting is completed. Y

, .The self-contained character of the construcand starting from the normal position of the parts, as shown in Figure 3, the disk member-3| commences rotationin counterclockwise direction, part'34 starts to .warp or bend the spring arm 32 in clockwise direction, the spring arm-32 Aand projection 36 meet,thusinterposing a resistance to continued swing of the arm 32 in clockwise direction and during that time inter;- val thecontinued counter-clockwise movement of -the` part 34 in effect bends the spring arm 32, thus storing energy in it, and when the member -32 finally by-passes the part 36, the striker 2| -withthespring arm 32 is thus suddenly snapped `completely-'to the left, as viewed in Figure 3,A

4striking the member 22 a sudden blow.

, Upon ,the retrograde movement of the button I9, under. .the expenditure of the energy previously stored in the spring 26, this snap action is repeated but now with the disk member 3I moving in clockwise direction and acting to warp i2() the spring arm 32 in counter-clockwise-direction, whence again the Aarm 32vencounters the projection 36 (but now on the left side of the latter) in order again to stress the spring arm 32'to causer it to distort enough to snap over the projection 36, whence the sounding element 23 is struckasudden blow. 5

1f .the two sounding elements are, as above noted, of diiferent pitch, the successive notes thus struck are of two different tones.

If the sounding element or elements take the lform .of chime bars, as in the illustrative embodiment, they may be mounted in any suitable way, preferably in lrelation to their nodes kand 'internodes, and with respectV to the point of strik- 535 .ing of the striker 2|; such suitable mounting means are diagrammati-cally indicated in Figures 1 and 3' by the reference character '31, rep- -resenting appropriate supports securedin anysuit- .able way, preferably to therplate I0. AvsheetY metal box-like cover 1 38, preferably 'apertured `or'louvered, as at 39, 'takes over the parts to the left `of the main plate- I0, as viewed in Figure 1, -and it preferably fits about the periphery of the plate `III! itself to which it is secured preferably detachably in any suitable way (not shown).

.The-apparatus, once assembled, will be 'seen Itolbe easy and quick to install, requiring no' in- `terferencewith its operating parts at all; a hole I2 (Figure 1) is drilled or cut in the panel' or Apart to which the device is to besecured, the

.sleeve II inserted through the hole and the'nut *|51 driven home, all as earlier above described,

'tion and `*its ease and simplicity of mounting, make-it possible to incorporate the mechanism into orwith `a hollow frame, like the frame of a door, as indicated in'Figure 6; thus, in Figure 6,

I.' have shown at 40', in horizontal cross-section, o

a vertical portion of a-hollow'sheet metal door frame of anyv ordinary or usual or suitable conformation illustratively conformed e to provide lmolding or trim portions 4I, 42 for'both the interior'and exterior, also rabbets A43, 44,-one of` rwhi `:h,lsuch :as the rabbet 43, takes the' door 45 which'mayfbehinged uponthe opposite and sim- 'ilarlyconformed vertical portion of the door ,lframe A'the wall construction, built up in any Fsuitable-way, is indicated at 46, and is built into theopriend of the hollow frame, all in the usual way. i 'But fat' .asuitable'height in the 'outsideface through whichis received, from the inside of related thereto. l ','Accordingm the device 5.5-52 may be mounted in position at the same timeand,in this preferred with openings, preferably louvered, as at 50, thus to permit free egressof sound from the interior of the door frame as `produced by the signaling apparatus.V The'door frame, when made of sheet metal, may, in the above described illustrative manner, be prefabricated, and the signaling apparatus assembled therewith at the factory or on the job, in the latter case, of course, prior to the closing up of the hollow frame bythe wall 46..

Thus, the signaling yapparatus is entirely out of the way, only the pushY button I9 being eX- posed from the door frame: the sounding mechanism itself is housed within Ythezhollow frame which, when, asis invariably the case, it becomes closed oif as by the wall 46, functions as Ia resonance chamber with respect to the sounding element or elements of the signaling equipment. it Vbeing optional as to vwhether or not the boxlikecover 38 therefor is employed in such case. The apparatus, furthermore, lends itself to manual'- actuation by means other than a 'depressible lpushbutton'; thus, for example, where push button actuation is not desired,4 I may provide a manual operating means of this type, illustratively like that, and preferably in the manner, shown in Figures 4 and 5, where I have shown a pivoted member 52 in simulation of a door knocker and,V in fact, capable ofifunctioning as such in the preferred construction. Thus, the member 52, which may be given any suitable configuration, particularly in so far as its lower portion 52a is concerned, is pivotally supported Aas byapin 53, between two spaced lugs 54 which are integrally formed with and are upstanding from a'b'ase plate 55 which suitable shape or outline, congurationzor decoration, and which, as is better shownin Figure 5, isprvided atits upperV of sufficient size to take over 4the sleeve member II, member 52 having'an upward extension 5 2b i which on its innerl'side or vface (left hand, as `viewed in Figure 5) is concave or hollcwed out coaiially or in line with the hole 56 and hence withy the sleevermember 'I,I when the ilatter is construction, bythe same means that mount the ,signaling` apparatus tothe supporting member,

such as the member I3 of Figure 1 or thepart 41 of Figure 6,. ,For, example, the sleeve II of the apparatus is put through the hole I2 in the -supportLpressing thelbase plate Il)k up against fthe left-hand face of the part I3, whence'the Ydevice V52-55, withthe Ynut I5 held over the hole 56, fispassed over the protrudingbutton'IS. the base plate portion 55 passed over thesleeve II which enters! through the'hole56, whence the nut I5 may be threaded onto the sleeve II and tightened up, leaving the assemblage in the Vform :shown in Figures 4' and-5 and with button I9 entered into'the hollow or concave portion of the cup-like end-*'52b fof the member 5-2', thus lcover,- -ing over and also, if desired, iobscuringthe 'butmay be givenA any Y portion with a hole 56 ton to any extent desired according to the configuration given the portion 52.*. i

`The parts are Apreferably so proportioned that,

with the button I9 projected outwardly Vunder `the action of spring I26,the,leverllke member -2, while thereby swung in clockwise direction and withits lower end portion 52 thus brought toward the base plate 55, is, nevertheless, held at aposition of rest such as to allowsome play between the lower end portion 52a and the base plate 55, somewhat as indicated in Figure 5.

With adequate play of this character thus provided, the member 52 may be used as a knocker, bytaking hold of the lower end and strikingit against the base, plate 55, while, upon pulling the lower end 52av outwardly, and a suitable instruction, such as the word Pull (see Figure 4) may vbe provided, if desired, the push button I9 is pressed inwardly against its spring |26 and upon release of the member 52 is returned outwardly, eifecting a repeated or successive actuation of the vsounding element or sounding elements, as was earlier above described. Y Thus, it will be seen that there has been provided in this invention a signaling apparatus in `might be made in the embodiment above s et forth, it is to be understood that `all matter here- 'inbefore set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense. i
